Ha! Truth. I have to admit that I never gain weight when I go away. I eat well, but, I don't eat a lot of rich food and almost never eat dessert. I actually am not a huge fan of sweet desserts.
I have lost 3-4 pounds since I left home. I have more time for myself, so I get in exercise every day and swim a lot more. Even if I did gain weight, it would be worth it! :)
